The 7 steps to durable wood repair
What do you need to carry out a durable wood repair? Below are not only the 7 steps to durable repair, but also what materials and tools you need as a professional for each step. This way, you can ensure your repairs last for years to come!
The 7 steps to durable wood repair
Remove paint
Common courses of action: Burning off, blow-drying (hot air) or sanding.
Materials and tools: Sander/burner/scraper/ blow dryer, dust mask and dustpan.
Remove all decay
Goal: Remove all affected wood to at least 5mm into the healthy wood. Always provide milling tray.
Common courses of action: Milling (flexible shaft, fixed router, battery-powered machine), sawing (oscillating saw) or chiselling.
Materials and tools: Mill/saw, spherical head router (9.5mm), safety glasses and sandpaper.
Measure wood moisture (≤ 18%)
Goal: To ensure that the wood moisture percentage is not above 18% and thus wood rot is still present in the repair.
Materials and tools: EASY•Q™ Wood Condition Meter.
Prime contact area with DRY FIX®
After sparingly applying DRY FIX®, allow it to penetrate for a minimum of 20 minutes and a maximum of 45 minutes. Then dab with a lint-free cloth to remove excess DRY FIX®.
Materials and tools: DRY FIX® UNI, EASY•Q™ MIX & FIX Cups, EASY•Q™ MIX & FIX Wooden Mixing Spatula and disposable brushes.
Butter contact area with DRY FLEX®/BIO FLEX™
Fire the repair with a thin layer of DRY FLEX® / BIO FLEX™.
Materials and tools: EASY•Q™ Buttering Knife, DRY FLEX® 1, 4, 16, SF or BIO FLEX™ COOL, ALLROUND, EASY•Q™ Mixing Plate and EASY•Q™ Dosing Gun (High Performance or single-ended)
Shape and finish repair
Make sure you build up the repair without air inclusion.
Chamfer the repair bulb.
Sanding finished repair and apply paint
- Drying delay paint at site of repair possible
- All types of paint possible. Advice to treat with primer within 2 weeks.
Good to know
Tips
- Cover the wall with EASY-Q™ Brick Tape.
- Use modelling strips (for polygonal repairs); they are easy to remove after curing.
Good to know
- Use EASY•Q™ Disposable Nitrile Gloves for safe working.
- Use EASY•Q™ Wipes for optimal tool cleaning.
- Use a paper towel to remove excess DRY FIX® and to dry the modelling knives.
Indicative curing times
In the table below you will find the indicative curing times (in hours) of Repair Care’s repair product.
Please note: the times mentioned are only an indication. Curing may vary due to temperature, layer thickness and humidity fluctuations, among others.
Explanation
DRY FLEX® and BIO FLEX™ products cure as a result of the chemical reaction between the A and B components. The factors affecting this curing process are mass and temperature.
- The more mass together, the faster it will cure. The less mass together (read: thinner layer), the slower the curing will be. For this reason, we also recommend keeping the resin thin and flat on the mixing pad during and after mixing and, when building up a repair, process the resin from the mixing pad and not from a modelling knife.
- The higher the temperature, the faster the mixed resin will cure. The lower the temperature, the slower the curing will be. At a temperature lower than 0˚C, no curing will take place. As far as temperature is concerned, consider not only the air temperature, but also the temperature of the repair surface itself and the influence of sun exposure after setting the repair.
